Abstract

Aqueous aerosol mousse compositions are disclosed which contain a silicone material dissolved in the aerosol propellant phase. Such compositions are not only easily processed but also provide for better dry combing than is obtainable if the silicone material is dispersed in the aqueous phase.

Description

TECHNICAL FIELD

The present invention relates to aqueous hair stying aerosol mousse compositions which provide excellent set hold as well as combing ease.

BACKGROUND OF THE INVENTION

The desire to have hair (human or other animal) retain a particular shape or configuration is one that is widely held. Approaches taken can either involve permanent alteration of the hair or a temporary alteration. The former involves the use of chemical agents to react with the hair in order to achieve the desired effect. This process can be carried out at either room or elevated temperature.
The temporatory set given to hair is, as the term indicates, a temporary arrangement which can be removed by water or by shampooing. The materials used to provide the set have generally been resins or gums. The temporary set compositions have taken the form of gels, lotions and sprays as well as others. The compositions are applied most often to hair dampened with water, combed or by other means spread through the hair and let dry. The set given will vary -depending on the materials used.
In recent years a form of a temporary set has been achieved by means of an aerosol foam -- a mousse. This form, which can easily be worked through the hair, can provide a set comparable to that given by a gel or a lotion. These products are generally applied to the user's hand and worked through the hair.
The conventional hair styling mousse, which got its start in .Europe, generally utilizes a water soluble polymer, water, possibly a conditioning agent, an emulsifier, aesthetic agents and the propellant. The conditioning agents used have included silicone type materials. Such formulations are disclosed in Billek, Doris E., "Aerosol Foam and Mousse Preparations in Europe", Cosmetics & Toiletries, Vol. 99 (September 1984), 57-60, 62-67.
The present invention involves the use of high molecular weight silicone materials in styling mousses. The formulae disclosed in Biliek, while containing silicone type agents, do not disclose high molecular weight materials or any materials dissolved in the propellant phase. A reference disclosing a variety of materials dissolved in the propellant phase prior to filling the container is Offenlegungsschrift DE 29 43 521, May 5, 1971. This reference does not however disclose high molecular weight silicone materials either. Such materials are however disclosed in non-aerosol hair conditioning formulations in U.S. Patent 4,387,090, June 7, 1983 to R. E. Bolich, Jr.
The present inventor has found that combining the silicone material with the propellant eliminates the need to mill the material, which would probably be necessary if it were to be combined with the aqueous phase. Additionally unexpected results have been found in hair conditioning (dry combing) and set hold when the material is in the propellant phase.
Therefore it is a purpose of the present invention to provide a superior hair styling mousse.
It is a further object of the present invention to provide a hair styling mousse employing a high molecular weight silicone material dissolved in the propellant phase.
These and other objects of the present invention will become readily apparent from the detailed description which follows.
All percentages and ratios used herein are by weight unless otherwise specified.

SUMMARY OF THE INVENTION

The present invention relates to aerosol compositions comprising water, a hair setting polymer soluble/dispersible in an aqueous phase and a solution of a high molecular weight silicone hair conditioning agent in a propellant phase.

DETAILED DESCRIPTION OF THE INVENTION

The essential as well as optional components are specified below.

Water

Water, preferably distilled or deionized, is the first essential component of the present invention. The water is generally present at a level of from about 55% to about 94%, preferably from about 80% to about 90% of the total composition.

Polymer

The polymer useful in the present compositions is any polymer soluble or colloidally dispersible in the aqueous phase (if water is the only solvent in the aqueous phase, the polymer should be soluble or dispersible in water; if an optional cosolvent such as ethanol is present the polymer should be soluble or dispersible in the combined solvent system). Solubility/ dispersibility is determined at ambient conditions (e.g., temperature about 25°C and atmospheric -pressure). Suitable types of polymers include anionic, nonionic, amphoteric and cationic. Specific polymers Include polyvinylpyrrolidone (PVP), copolymers of (PVP) and methylmethacrylate, copolymers of PVP and vinylacetate (VA), polyvinyl alcohol (PVA), copolymers of PVA and crotonic acid, copolymers of PVA and maleic anhydride, hydroxypropyl cellulose, hydroxypropyl guar gum, sodium polystyrene sulfonate, PVP/ ethylmethacrylatelmethacrylic acid terpolymer and octylacryl- amide/acrylate/butylaminoethyl methacrylate copolymers. PVP and PVP copolymers with other monomers are preferred.
Mixtures of polymers may also be used. With certain of the polymers it may be necessary to neutralize some acidic groups to promote soubility/dispersibility (e.g., PVA/crotonic acid).
The polymer(s) is used at a level of from about 0.5% to about 10%, preferably from about 1% to about 6% of the total composition. The mass average molecular weight of the polymer is not critical but is generally in the range of from about 2,000 to about 2,000,000.

Propellant

The agent responsible for expelling the other materials from the container and forming the mousse character is a propellant.
The propellant gas can be any liquefiable gas conventionally used for aerosol containers. Preferably the density of the propellant or mixture thereof is less than 1 so that pure propellant is not emitted from the container. Examples of materials that are suitable for use as propellants are trichlorofluoromethane, dichlorodifluoromethane, dichlorotetrafluoroethane, monochlorodifluoromethane, trichlorotrifluoroethane, dimethylether, propane, n-butane and isobutane, used singly or admixed. The hydrocarbons, particularly isobutane, used singly or admixed with other hydrocarbons, are preferred due to their densities being less than 1.
The amount of the propellant gas is governed by normal factors well known in the aerosol art. For mousses the level of propellant is generally from about 5% to about 20%, preferably from about 7% to about 15% of the total composition. If a propellant such as dimethylether utilizes a vapor pressure suppressant (e.g., trichloroethane or dichloromethane) the amount of suppressant is Included as part of the propellant.

High Molecular Weight Silicone Material

The agent providing hair conditioning (e.g., dry hair combing) is a high molecular weight silicone material. References disclosing such silicones are U.S. Patent 4,152,416, May 1, 1979 to Spitzer, et al.; Silicon Compounds, distributed by Petrarch Systems; and Noll, Waiter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Also describing high molecular weight silicone materials are General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76. These references are incorporated herein by reference.
Because of the ready availability of equipment and the simplicity of the method, commercial manufacturers generally characterize high molecular weight silicones by their viscosity or in some cases by a penetration value. High molecular weight silicone materials denotes polydiorganosiloxanes having a viscosity of at least 100,000 centistokes, preferably from about 10⁵ to about 15 x 10⁶. Specific examples include polydimethylsiloxane, methylphenyl-diphenyl siloxane copolymer, (potydimethylsiloxane) (methylvinylsiloxane) copolymer and poly[dimethylsiloxane) (diphenyl) (methylvinylsiloxane) copolymer and mixtures of these agents. The silicone material is generally present at a level of from about 0.05% to about 2%, preferably from about 0.1% to about 1% by weight of the total composition.

Optional Components

The aerosol mousses herein can contain a variety of nones- sential, optional components suitable for rendering such compositions more acceptable. Such conventional optional ingredients are well known to those skilled in the art, e.g., emulsifiers such as anionics (e.g., sodium alkyl sulfate) and nonionics (amine oxides); preservatives such as benzyl alcohol, methyl paraben, propyl paraben and imidazolidinyl urea; cationic emulsifiers/conditioners such as cetyl trimethyl ammonium chloride, stearyl- dimethyl benzyl ammonium chloride, and di(partially hydrogenated tallow) dimethylammonium chloride; thickeners and viscosity modifiers such as a diethanolamide of a long chain fatty acid; block polymers of ethylene oxide and propylene oxide such as Pluronic F88 offered by BASF Wyandotte, fatty alcohols such as cetearyl alcohol, sodium chloride, sodium sulfate, and ethyl alcohol; pH adjusting agents such as citric acid, succinic acid, sodium hydroxide and triethanolamine; coloring agents such as any of the FD&C or D&C dyes; hair oxidizing (bleaching) agents such as hydrogen peroxide, perborate salts and persulfate salts; hair reducing agents such as the thioglycolates; perfume oils; chelating agents such as ethylenediamine tetracetic acid; and, among many other agents, polymer plasticizing agents such as glycerin and propylene glycol. These optional materials are generally used individually at a level of from about 0.01% to about 10%, preferably from about 0.5% to about 5% by weight of the total- composition.
Another optional component preferred for use herein is a low viscosity silicone fluid to be used along with the high molecular weight silicone material in the propellant phase. Such materials may be either a polyalkyl siloxane, a polyaryl siloxane, a poly- alkylaryl siloxane or a polyether siloxane copolymer. These materials preferably have a viscosity of from about 5 to about 10,000 centistokes, most preferably from about 100 to about 1,000 centistokes, at 25°C. The agent is preferably used at a level of from about 0.1% to about 1% by weight of the total composition.

METHOD OF MANUFACTURE

The method of preparing the aerosol compositions of the present invention follows conventional aerosol filling procedures. The water soluble or dispersible materials (not including the silicone material) are mixed with water to form a "concentrate". This concentrate, in an appropriate amount, is placed into an aerosol container. The container is then fitted with a valve, subjected to a vacuum to rid the container of air and sealed with the valve "crimped" in place. The silicone material is then mixed with the propellant fluid and the propellant/silicone mixture is filled into the container through the valve.

INDUSTRIAL APPLICABILITY

The present compositions are emitted from the aerosol container as a foam which is then worked through the hair with the fingers or a hair styling implement and either left on the hair or rinsed out.
